Question: 1 / 400

What does the inlet location of a ventricular septal defect refer to?

Near the aorta

Near the pulmonary artery

Near the mitral and tricuspid valves

The inlet location of a ventricular septal defect (VSD) specifically refers to the area near the mitral and tricuspid valves. VSDs in this location are typically classified as "inlet" or "atrioventricular septal defects" and are often associated with anomalies of the atrioventricular valves. This defect position is of particular clinical importance because it may influence the hemodynamics of blood flow between the ventricles and can affect the function of the valves, leading to potential complications such as valve regurgitation.

Inlet VSDs are distinct from other types of VSDs, such as those located near the aorta or pulmonary artery. Understanding the anatomy of the heart and the specific location of congenital defects is crucial for diagnosis and planning surgical repair, as the inlet location is intimately related to the surrounding structures and their functions.
